Answer:

Rate = 12345.67 (cubic foot per second)

Flow rate = 49.3826

Step-by-step explanation:

Computation:

7.5 gallons = 1 cubic foot

1 gallon = 1 / 7.5 cubic foot

So,

8 billion gallon = (8 / 7.5) billion cubic foot

Rate = [8/(7.5 × 24123456 × 60 × 60)]

Rate = 12345.67 (cubic foot per second)

Flow rate = (12345.67/25,000) 100

Flow rate = 49.3826
